Freshman Democratic Sen. Bob Casey of Pennsylvania was re-elected Tuesday, according to a CNN projection. The win preserves a seat for Democrats in the narrowly divided chamber that Republicans had hopes late in the race of winning.

GOP candidate Tom Smith, a wealthy business executive, lagged far behind Casey for much of the race. But in the last few weeks he spent heavily on advertising and was able to narrow the polls but never take the lead.

CNN’s projection of President Barack Obama winning Pennsylvania comes after a tug-of-war in a state that seemed for months to be a lock for Democrats.

Polling in recent weeks showed the race tightening in the Keystone State, and one of the top surrogates for the president – Bill Clinton – made a campaign swing through Pennsylvania to try and shore up support there.

Seeing an opening, Mitt Romney and his running mate Paul Ryan both went there for campaign swings, and even on Election Day, Mitt Romney made a stop in Pittsburgh to try and bolster his shot of taking the state’s 20 electoral votes.

The campaigns also went on the air there, starting a television ad war in the last weeks, despite not having advertised in the state for most of the election.
